Which specific training expertise involving spacecraft environment preparation will ESA provide to ISRO astronauts?

Microgravity training essential for preparing crews for long-duration stays aboard a spacecraft.

The collaboration explicitly involves ESA providing expertise to ISRO astronauts in areas critical for long-duration space missions, most notably microgravity training. This type of preparation is essential because it acclimates the crew to the operational environment they will experience aboard the spacecraft for extended periods. By incorporating ESA's established protocols, which have been refined through decades of experience on missions such as the International Space Station (ISS) and Soyuz flights, ISRO gains an invaluable shortcut in rapidly maturing its astronaut corps capabilities for the upcoming Gaganyaan flights.
